If an ISDN / Analogue recorder is being used then click OK at the Call Recorder Installer window. This
appears before the installer package installs the USB driver.
In the Windows Security Window, choose the option to 'Install this driver software anyway.' This will
allow the drivers for the USB recording to be installed.
Click next on the Product Information prompt, this information is used by the client application. This
uses the default database configuration.
